CFD modelling of a pulsed jet formed during an idealized isolated cough [PDF]

open access: yesE3S Web of Conferences, 2022
The current contribution presents the results of calculations of a pulsed jet formation during a single cough based on the recent test by Fabregat et al. (2021) where the DNS of an idealized isolated cough was performed.

Magnetic nanoparticle hyperthermia for treating locally advanced unresectable and borderline resectable pancreatic cancers: the role of tumor size and eddy-current heating

open access: yesInternational Journal of Hyperthermia, 2020
Purpose Tumor volume largely determines the success of local control of borderline resectable and locally advanced pancreatic cancer with current therapy. We hypothesized that a tumor-mass normalized dose of magnetic nanoparticle hyperthermia (MNPH) with

Flaws characterization with pulsed eddy currents NDT [PDF]

open access: yesIEEE Transactions on Magnetics, 1999
In this paper, we present a method for characterizing flaws in metallic structures with pulsed eddy current nondestructive testing (NDT). In a first step, we explain why we have chosen a deconvolution method based on conjugate gradient algorithm (CG).
